We have developed shelf- and air-stable ortho-stannylated aniline reagents that can directly be coupled with alkenyl and aryl halides via Migita–Kosugi–Stille cross-coupling. We report (i) the efficient preparation of o-(tributylstannyl)aniline (2a) and o-(trimethylstannyl)aniline (2b), (ii) the comparison of the reactivities of 2a and 2b with those of related organostannanes in cross-coupling reaction
我们开发了耐贮存和空气稳定的邻甲锡烷基化苯胺试剂,可通过 Migita-Kosugi-Stille 交叉偶联直接与烯基和芳基卤化物偶联。我们报告(i)的有效制备ø - (三丁基锡烷基)苯胺(图2a)和ø - (三甲基锡烷基)苯胺(图2b),(ii)所述的反应性的比较图2a和2b中,在交叉偶联的那些相关的有机锡烷的与烯基卤化物反应,以及 (iii) 2a和2b与一系列芳基卤化物和三氟甲磺酸酯的交叉偶联。
